Abstract: 1412435 Memory cells HONEYWELL INFORMATION SYSTEMS Inc 3 Nov 1972 [3 Nov 1971] 50888/72 Heading H3T A memory cell comprises first and second transistors 14, 16 having their main current paths connected in series between a terminal 23 and a common input/output terminal 21, a third transistor 12 having its main current path connected between the control electrode of transistor 14 and the terminal 21, a charge storage arrangement, e.g. a capacitor 10, a selection terminal 19 connected to the control electrodes of transistors 16, 12, and a read-write cycle determining arrangement (not shown) for placing an initial charge on terminal 21 and a control potential on terminal 23. In operation, during the " read " period, the selection voltage at 19 is adequate to turn on transistor 18 but not transistor 12 and a change, absence of change of voltage at the terminal 21 is indicative respectively of the storing of a " 1 " or a " 0 " in the storage capacitor 10. In the absence of an external write signal, during the " write " period the charge on the capacitor 10 is altered to its complementary value by current flowing from line 22 via the now conducting transistor 12. However, an external circuit (Fig. 2, not shown) including a flip-flop inverts the voltage level on line 22 and re-applies it to line 22 so as to restore the initial charge on capacitor 10. When a different information is desired to be written in, the voltage level on line 22 is suitably altered by an external write signal and the charge on capacitor 10 is correspondingly altered via transistor 12. The restore period is arranged to precede the writing in of external information. A number of memory cells may be connected up in a matrix.

Abstract: 1,075,136. Spreading granular material. DEERE & CO. Dec. 18, 1964 [Dec. 20, 1963], No. 51573/64. Heading A1D. In a spreader for broadcasting fertilizer, seed or other materials, the material is fed from a hopper 12, Fig. 1, by a conveyer 20 past an adjustable gate 56 and via a shoot 50 on to a spinner 18. The shoot has a curved lower edge portion 78, Fig. 14, to deposit the material in an arcuate pattern near the centre of the spinner, and gathering fins 76 which cause more material to be deposited in the central portion of the arc; this ensures an even distribution of the material when it is scatered by the spinner in an arcuate pattern over the ground. Since the angle between deposit on the spinner and discharge depends on the nature of the material, to ensure that this latter pattern may be symmetrical the spinner shaft housing is transversely adjustable relative to the shoot in accordance with the material being spread. The spinner comprises four S-shaped blades, Fig. 3, extending radially from a conical central portion 62, Fig. 5, the design being such as to accelerate the particles of material uniformly. The spinner and conveyer are driven through chain-and-sprocket gearing from a shaft 22 connected through a clutch to a ground wheel 16. The spinner drive is through a governor-controlled transmission, Fig. 5, between a shaft 80 and the spinner shaft 82 (these shafts being at right angles to each other and not parallel as shown). Each shaft carries a fixed pulley half 90 or 106 and a slidable half 92 or 108, the spacing of the halves determining the speed ratio transmitted by the V-belt 88. The centrifugal governor comprises four weights 116 each comprising an inner roller which rolls on a track on the pulley half 108 and two outer rollers which rolls on the conical under-surface 118 of the spinner. The conveyer drive is through a further clutch. Fig. 17, on the shaft 22 comprising a slidable spool 156 having teeth 164 engaging teeth 166 on a sprocket 168. The spool is engaged by the end 155 of a spring lever 154 which is opterated to disengage the clutch by rotating rectangular cams 192 through a ratchet (not shown) from an arm 194 actuated by a rope 196.

Solid or hollow thermoplastic extrudate is sized and cooled using a sizing die 23 comprising abutting porous annulµ 26a-26e and 27a-27e, the former set 26a-26e each providing a cavity connected to a source of cooling liquid, e.g. water, via a conduit 29, the cavities being sealed peripherally by metal plates 28a-28e and laterally by coatings, e.g. of resin, on the exposed surfaces of annulae 27a-27e. In operation, die 23 is immersed in cooling liquid within a tank (4), Fig. 1 (not shown), which liquid is fed to the tank via a valve (11) and maintained at a pressure below atmospheric by a vacuum system comprising a pump (8) and Venturi (9).
